COMBINED "SPAHRKARRESTER AND FLUE-SUPPORTER.

SPECIFICATION forming part of Letters Patent No. 293,357, dated February12, 1884.

Application filed September 8,1883. (No model.)

Toall whom it may concern..-

-Be it known that I, .IosEPH O. RIDLEY, of the city of St. Louis, in theState of Missouri, have invented acertain new and useful Improvement ina Combined Spark-Arrester and Flue-Supporter for Boilers, of which thefol especially intended for use on locomotive-boilers, whose office isto arrest the sparks and at the same time form a support to the flues ator near the center of the boiler.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Referring to the drawings, A represents a boiler and B the fluesthereof. The boiler is constructed as usual, but the flues are made intwo sections each, their adjacent ends connecting with a box or chamber,0, or, in otherwords, one set of flues connect the box with the front ofthe boiler and another set of flues boiler.

tending downward a suitable distance, discharging at a suitable point,such as the ashbox. It is preferably provided with a valve, J, operatedby suitable means, by which it can be opened and closed at will.

As a means for operating the valve I have shown a bell-crank lever, L,pivoted to the front of the boiler, which has a rod, L, for operatingit, andwhich is connected, by means of a rod, L to a crank, I, on theshaft of the valve. The inside of the box or chamber is provided with adeflector, O, at theend nearest the fire-box, and it is also preferablypro vided with a second deflector, 0 near the other end. The firstdeflector extends from the top downward a suitable distance, and acts toprecipitate the sparks, cinders, &c., as they enter the chamber throughthe flues. The second deflector extends from near the bottom of thechamber upward a suitable distance, and acts as a stop to any sparks andcinders that may have a tendency to rise from the lower part of thechamber upward. It will thus be seen that my device acts both as aspark-arrester and a flue-supporter, preventing sparksfrom escapingthrough the smokestack and preventing the flues from sagging in themiddle. as they are apt to do when not supported. The cinders, &c., aretaken from the boxor chamber through means of the pipe I, whichdischarges them at a suitable point; or they may be taken therefrom byother suitable means.

I claim as my invention- 1. In a steam-boiler, the combination, with achamber, divided flues connected thereto, and a discharge at the bottomof the chamber, of a deflector depending from the top of the chamber atthe end nearest to the fire-box, to

pipe, as set forth. 7

2. Ina steam-boiler, the combination, with a chamber, flues connectedthereby, and a discharge at the bottom of the chamber, of the deflectorprojecting upward from the bottom of the chamber to throw the solidmatter back into the discharge-pipe, as set forth.

3. In a steam-boiler, the combination, with a chamber, fiues connectedthereby, and a discharge at the bottom of the chamber, of the dependingdeflector at the end of the chamber nearest to the fire-box, and adeflector extending upwardly from the bottom of the chamher in advanceof the discharge-pipaas set forth.
